ORRIN H. GOODRIOI-I, OF OASTLETON CORNERS, NEW YORK, ASSIGNOR TO THE MINIATURE TELEPHONE BOOTH 00., OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

APPLIANCE FOR USE WITH TELEPHONE-TRANSMITTERS.

To all whom it may concern: Be it known that I, ORRIN H. Goonnion, a

citizen of the United States, and resident of Castleton Corners, Staten Island, county of Richmond, and State of New York, have made-a new and useful Invention in Appliances for Use with Telephone-Transmitters, of which the following is a specification.

My invention is directed particularly to an improvement upon the invention disclosed in a prior patent granted to me on the 25th day of August, 1908, numbered 897,084, and it has for its objects, first, to simplify, cheapen and render more efficient those parts of the mechanism whereby the receiving telephone is caused to actuate the switch as it is hung upon or removed from the switch actuating lever exterior to the inclosing easing or box. Second, to make it possible for an inspector or other authorized person to more readily detach the portable telephone, transmitter, receiver and interconnected attachments from the inclosing casing or box and with the least ossible annoyance and inconvenience. Thir to effect an adjustability of all of the switch operating parts to such an extent as to make the same a plicable for use with telephone receivers 0 different weight and also with portable transmitters where the switch actuating arm may be located at variable heights, thereby adapting the inclosing casin or box for use with various types of porta le telephones.

My inventlon will be fully understood by reference to the accompanying drawings, in which, v

Figure 1 is ,a side elevational view illustrating the inclosing casing or box complete and the switch actuating and controlling appliances in full lines, a portion of the side of the box being broken away to better illustrate a part of the adjusting ap liances; the portable telephone transmitter ocated within the casing or box being shown in dotted lines, as is a so a portion of the flexible conductors runnin to the suspended receiver exterior to the ox. Fig. 2 is adetail part sectional, part plan, view of the improved switch controlling devices and Fi 3 is a part sectional, part side elevational view of the means for adapting the switch control ling devices for use in connection with port able telephone transmitters where the switch actuating levers are located at various heights upon the standard of the transmit- Speeification 01' Letters Patent.

ting telephone, or where adjustability of the switch controlling parts is found necessary.

Referring now to the drawings in detail and first to Fig. 1, 1 represents the standard of a well known portable or desk telephone provided with a transmitter 2 hinged at the top thereof, 3 being the receiver, also of well known form, and 1 (Big. 2) the usual spring actuated circuit switching lever provided with forks 5 and (3 for supporting the receiver. The transmitter, receiver and switch appliances are connected up with the usual flexible conductors 30, the entire outfit being of well known form. 7 represents the inclosing casing or box provided with a door on its front side and a transmission opening 8 secured thereto in front of the transmitter 2, 9 beinga flexible ring secured in the transmission opening and having substantially the contour of the lower portion of a ersons face, this feature being substantially ike that disclosed in the before-mentioned patent.

The door which supports the transmission opening 8 and flexible ring 9 is hinged or otherwise secured at its top or bottom to the box and is provided with any preferred means for locking or securing it when closed, such, for instance, as one or more buttons or hooks, or a staple and paddock.

10 represents a rotary shaft j ournaled in a journal bearing 11 secured by screws extending through its enlarged head in an opening in one of the sides of the box.

12 is a circuit changing arm )rovided with forks 13, 14, similar to the for {S 5 and 6 of the circuit changing lever l, its function being to sustain the telephone receiver 3 outside the casing or box, said lever being se cured directly to the shaft 10 by a set-screw 15, or in any preferred manner. ner end of the shaft 10 is secured by a setscrew 17 an angular arm 16, 18 being a flange for adjusting the position of the arm upon the shaft 10.

19 is a spiral spring secured at one end by a screw-eye 20 to the inner surface of the easing or box 7, the other end of said spring being attached to a slidable rod or pin 22 screw-threaded at its free end and adz ted to be adjustably secured through a hoe or opening 23 in the angular arm 16 through the agency of a screw-nut 21, the arrangement being such that a variable tension may be put upon the spring 19 after the end of the arm 16 has been inserted through one To the in- I of the eyes of the forks 5, 6, thus making the any emission of such sound waves after the circuit changing attachments adjustable so as to better assure the free operation of the switch lever 4 in accordance with the weight of the telephone receiver 3 when hung upon or removed from the forks 13, 14.

In Fig- 3 of the drawings 1 have illustrated novel means for effecting an adjustment of the switch operating parts so as to accommodate the same for use with portable telephones in which the switch actuating lever 4 may be located at different heights, the same consisting of a lug or ear 2% adapted to be secured directly to the free end of the angular arm 16 by a set-screw, and in turn adjustably secured to a metal bar 25 slotted longitudinally as at 26, through the agency of screws, 27, 28 being an enlarged extension adapted to bridge the space between thetwo ends of the forks 5, 6 in the same manner as the like parts are bridged in the abovenamed' patent. With such an arrangement it is apparent that by releasing the screws 27, 27 the parts may be adjusted so as to adapt the arts hereinbefore described to portable te ephones of various structure, and in which the circuit changing levers may be located at different heights. 29 is a stop at the outer end of the journal bearing 11 for checking the downward movement of the switch arm 12 whenthe telephone 3 is hung upon said arm. 31 represents a slot in one of the side faces of the casing or-box, said slot being for the purpose of detachably inserting the conductors 30, a similar slot being provided on the opposite side of the box for receiving in like manner the flexible conductors running from the transmitter and call circuit to the line wire and bell circuit; or both sets of conductors might, if preferred, ass out of the single slot 31 and said slot or s ots may be closed by inserting soft rubber or other plugs, or in any preferred way, after the conductors are inserted.

It will be'apparent that with the above described improvement the door may be opened and that a line inspector or other authorized person may remove the transmitter from the inside of the box by simply lifting it out of the supporting ring shown at the bottom in dotted lines, and then advancing it toward the door, as illustrated by the arrow in Fig. 2. At the same time the re ceiver may be lifted from the hook and the entire outfit and interconnections be held disconnected from the box, thus enabling such inspector to fully inspect, and if need be repair, any part of the telephone outfit.

It is also obvious that with such an ar rangement of switch operating parts the best mechanical and electrical effects are had, and that the sound waves issuing from the mouth of the person transmitting will all be effectually retained within the box, there being no opening'or openings by which there'may be user has effectually seated the lower portion of his face against the flexible ring 9 in the transmission opening 8.

Having thus described my invention what I claim and desire to secure by Letters Patent of the United States is 1. An inclosing telephone casing or box having a transmission opening adapted to be located in front of an inclosed transmitter provided with a circuit changing-switch; in combination with pivotally actuated means exterior to the box for yieldingly supporting the telephone receiver, and an arm secured thereto but within the box adapted to make mechanical connection with the circuit changing switch, substantially as described.
